Speaking to Denver reporters during a conference call Tuesday, O’Brien denied that story, claiming he never made such a statement.

After practice Wednesday, Keenum was asked about O’Brien denying the quarterback’s version of the story.

“I outlined it in my book,” Keenum said. “I think it was Chapter 11, if you guys want to go check that out. I said that how I wanted to say it in the book.”

Keenum went on to praise O’Brien and all of his previous coaches.

“Whatever it was that was said motivated me,” Keenum said. “It got me going and every coach I’ve ever had they’ve gotten me to where I am now. I’ve got the utmost respect for him and the whole Texans organization.”
